Description

The present invention relates to a protection device equipping an opening defined at the level of a construction.

This invention relates to the field of the building and, more particularly, that of the manufacture of protective devices that equip an opening defined at such a building.

This invention will find a particular application in the context of a roller shutter, a garage door, a blind, a mosquito net or the like, equipping an opening of a building and having an apron and backstage sideways within which move the lateral ends of this apron.

In known manner, such an apron may be constituted by a plurality of blades whose longitudinal edges comprise means for assembling, in particular by interlocking or threading, these blades.

Such apron comprises, on the one hand and at its free end, a final blade which, in the deployed position of the apron, is positioned close to, or in contact with, the threshold of the opening closed by this apron and, on the other hand, a first blade secured to a winding shaft on which is wound and from which the deck is unwound.

In this regard, it will be observed that, during an intrusion attempt inside the building, an intruder acts, usually, under the final blade to try to lift the deck in order to cause a winding of this deck on the winding shaft and thus to clear the opening to be able to enter the building.

In fact, when the apron is fully deployed, the blades of the apron are joined so that the deck forms a rigid assembly that can be lifted as a single block.

In order to prevent such an uplift, different systems have been devised consisting, for one, in a locking system in rotation of the winding shaft, for the other, in an automatic locking system, in particular constituted by blades connecting the deck to the winding shaft and likely to switch to a position ensuring a blocking of the deck.

However, the blades of such an apron can be made so as to present openings allowing the passage of daylight through this apron. Also and when such an apron is closed on openings, this apron is deployed only partially (although over the entire height of the opening) and so that the blades are not contiguous.

Also and in case of intrusion, the intruder, acting on the final blade, is likely to lift the deck at least sufficiently to allow him to sneak under the deck and enter the building through the opening , despite the possible presence of an anti-lift system of the type mentioned above.

In the document FR-2822884 there is described a protective device adopting the form of a mosquito net constituted, on the one hand, by an apron comprising a final blade and, on the other hand, by lateral slides in which the lateral edges of this apron, especially this final blade.

This protection device comprises, again, a means designed to ensure the locking of the deck in its deployed position.

Such locking means comprises, on the one hand, a slider secured to the final blade and designed to adopt a translation movement relative to this final blade and with respect to a lateral slide. This slider is provided with attachment means extending laterally with respect to this slider, on either side thereof.

On the other hand, this locking means further comprises and at the level of the lateral slide stop stops with which cooperate the catching means equipping the slider for an immobilization of the deck in the deployed position.

On the other hand, this locking means comprises means for guiding the catching means of the slider, as the case may be, in the direction of the stops to cooperate with them in order to lock the apron in the deployed position. or away from these stoppers for unlocking the apron.

It will be observed that, as well to lock as to unlock the deck, the guidance of these attachment means is in two stages, a first time during which it is exerted an action on the deck tending to deploy it followed by a second time during which the apron is subjected to an elastic return means tending to fold the apron.

In fact, such a protection device has a number of disadvantages.

Thus, the slider is sliding type and adopts a back and forth movement, this on a relatively long race on which this slider is subjected to friction phenomena detrimental to proper movement of the cursor.

In addition, these phenomena of friction over a large stroke length result in premature wear and premature sliding mounting means of the slider on the final blade.

In addition, this slider opens out of this final blade over a long length at which this slider is subject to fouling phenomena.

These phenomena of friction, wear and fouling prevent proper sliding of the slider, or even cause a blockage thereof, which usually results in immobilization of the deck in an extended position or in the impossibility of achieving a lock of this apron.

Another disadvantage is that the guiding means of this slider as well as the stops are, on the one hand, of design and, therefore, of rather complex shape because of the particular displacement which they must confer on this slider to ensure the locking / unlocking of the apron and, secondly, relatively subject to the phenomenon of fouling due, in particular, their complex shape.

In addition, during the guiding of the slider and its attachment means, friction phenomena occur at these and at the level of the guide means and the stops, these friction being translated by wear of the locking means detrimental to its proper functioning.

Finally, the design of these guide means, these stops, this slider and sliding mounting means is provided to allow proper and easy movement of the slider, which is, in fact, provided at the expense of mechanical strength locking means.

The present invention is intended to overcome the disadvantages of protection devices of the state of the art.

To this end, the invention relates to a protective device of the garage door type, blind, shutter, mosquito net or the like, equipping an opening defined at a construction and having an apron, side slides in which move the lateral ends of the deck and at least one deck locking means in the deployed position and formed, on the one hand, by a lock associated with the deck and designed to adopt a locking position and an unlocking position on the other hand, by a stopper associated with a lateral slide and with which the latch cooperates in its locking position and, secondly, a means for controlling the passage of the latch at least one position. locking device at an unlocking position, characterized in that the latch is at least of rotary type and is secured to the deck by means of a rotational mounting means of This lock is between the locking and unlocking positions while the control means is adapted to control the rotation of the latch from at least one locking position to an unlocking position.

According to another characteristic, the latch comprises at least one latching means which, in latch locking position, extends laterally with respect to the plane in which the apron extends, in order to cooperate with the stopper.

An additional feature is that the means for mounting the lock in rotation comprises or is defined at an insert, engaged within a blade that the apron has and relative to which the lock is mounted at least in rotation.

Another feature is that the stopper comprises at least one bearing surface defined at a rib extending inside a lateral slide and with which the latch cooperates.

According to an additional feature, the device comprises at least one locking block, engaged inside a lateral slide, positioned at the lower end thereof, and at which at least one stop is defined. stopping a locking means.

In addition, this device comprises means for controlling the rotation of the lock from an unlocking position to a locking position.

In this regard, it will be observed that the control of the rotation of this lock (from a locking position to an unlocking position and / or vice versa) is ensured under the effect of the movement of the deck, more particularly under the effect of the deployment and / or folding of this apron.

According to a first embodiment, the lock is of rotary type and comprises at least one attachment means designed to cooperate with a stop in the locking position while the locking means comprises a shaft associated with such means. as well as to the apron by means of a mounting means.

According to a second type of embodiment, the rotary type lock is, moreover, sliding type relative to the deck and is secured to this deck by means of a translational mounting means, completing the mounting means in rotation of this lock.

The advantages of the present invention are that the characteristics of the protective device according to the invention are relatively general so that they can be transposed to a plurality of protection devices. Such a protective device can then adopt different embodiments and be, in particular, constituted by a garage door, a shutter, a blind, a mosquito net or the like.

Advantageously, such a protective device is constituted by a roller shutter, more particularly whose apron is constituted by a plurality of blades may be closed on ajour.

Another advantage of the invention is that the means for controlling the rotation of the latch can, at least in part, be actuated under the effect of the sole weight of the deck (in particular in the case of a shutter or the like ) or the final blade (especially in the case of a mosquito net or the like).

Whatever the embodiment of the protective device it comprises a winding shaft on which is wound and from which the deck is unwound. Such a winding shaft is associated with a winding mechanism which, advantageously, can be of manual type (winch, strap, direct draw ...) and / or motorized.

Another advantage of the invention is that the travel (vertical) of the deck with which the lock is associated to bring the latter into a locking position and / or unlocking is particularly short and can advantageously be limited to that necessary to ensure the crushing of a seal fitted to an end element (final blade or the like) of the deck, unlike the (horizontal) stroke of the lock of a device of the state of the art which requires, to seal the apron, to associate, with an end element, a telescopic blade provided with a seal.

Other objects and advantages of the present invention will become apparent from the following description relating to embodiments which are given by way of indicative and non-limiting examples.

The present invention relates to the field of building and, more particularly, that of the manufacture of protection coming to equip a defined opening at such a building and designed to ensure the protection of this building and / or its occupants, including against an undesirable phenomenon.

Such a building is in the form of a construction 1 at the level of which are provided openings 2 capable of receiving a protective device 3.

In this regard, it should be noted that, in the remainder of the description, reference will be made more particularly to a protective device 3 consisting of a shutter 4, knowing that the present invention is not, in any way, limited and such a protective device 3 may, again, be in the form of a garage door, a blind, a mosquito net or other.

Such a protective device 3 comprises, on the one hand, an apron 5 designed to extend over at least part (or even preferably all) of the height of the opening 2.

This apron 5, in the case of a shutter 4, a garage door or the like, is constituted by a plurality of blades 6 assembled, in particular by interlocking and / or threading.

However, and according to another embodiment corresponding, in particular, to a blind, a mosquito net or the like, such an apron 5 may, in part, be constituted by a cloth part (blind) or by a fine mesh mesh (mosquito net ).

Whatever the embodiment, such a deck 5 has a free end 7, usually located in the lower part of the deck 5 when the latter is in the deployed position, at which 7 this apron 5 comprises an end element. 8, more particularly consisting of a final blade or the like.

Such a protective device 3 comprises, on the other hand, a means 9, to which this apron 5 is connected, positioned in the upper part of the opening 2, and designed to ensure, on the one hand, the winding of this apron 5 for its folding and, secondly, the unfolding of the apron 5 for deployment.

Such winding / unwinding means 9 comprises, on the one hand, a winding shaft on which rolls and from which said deck 5 unwinds and, on the other hand, a mechanism for driving this shaft. winding.

In this respect, it will be observed that such a drive mechanism can be of the manual type (in particular in the form of a winch, a chain, a strap, a direct pull or the like) or of the type motorized (in particular in the form of an electric motor, more particularly associated with support means of this shaft or, at least in part, engaged inside this shaft).

It will be observed that this drive mechanism may, according to a particular characteristic of the invention, still comprise a return means designed to ensure, automatically, a winding (in the folded position) of this apron 5 on this winding shaft .

On the other hand, this protection device 3 comprises lateral slides 10, 10 'fitted to the lateral edges of the opening 2 receiving this protection device 3, and extending over at least part (preferably, and preferably on the whole) of the height of this opening 2. Such a lateral slide 10, 10 'has, usually, a U-shaped section and comprises a bottom and two lateral wings, extending from this bottom, and delimiting an opening for the passage of the apron 5.

It is, more particularly, within these lateral slides 10; 10 'that move the lateral ends 11; 11 'of the apron 5, this during a deployment maneuver / folding this apron 5.

This protection device 3 comprises, again, at least one means 12, 12 'for locking the apron 5 in the deployed position.

In this regard, it will be observed that such a protection device 3 may comprise a single locking means 12 located at one side of this device 3 but preferably comprises and as visible figure 1 two locking means 12, 12 'located on one side and the other of this protection device 3.

Such locking means 12 is constituted, on the one hand, by a latch 13 associated with the apron 5 and designed to adopt a locking position and an unlocking position.

On the other hand, such a locking means 12 is constituted by a stopper 14 associated with a lateral slide 10. It is, more particularly, with such a stopper 14 that the latch 13 cooperates in its position. locking.

On the other hand, such a locking means 12 is constituted by means 15 for controlling the passage of the latch 13 at least from a locking position to an unlocking position.

According to the invention, the latch 13 is at least of rotary type and is secured to the deck 5 by means 16 for mounting in rotation of the latch 13 between the locking and unlocking positions while the means of control 15 is adapted to control the rotation of the latch 13 to less than a lock position to an unlock position.

In this regard, it will be observed that the control of the rotation of this latch 13 is ensured under the effect of the displacement of the deck 5, more particularly under the effect of the deployment and / or folding of the deck 5.

Another feature of this latch 13 is that it comprises at least one attachment means 17 which, in the locking position of the latch 13, extends laterally with respect to the plane in which the apron 5 extends, this to cooperate with the stopper 14.

Regarding the means 16 for mounting the latch 13 in rotation, the latter 16 comprises or is defined at the level of an insert 18, engaged inside a blade 6 that the apron 5 (more particularly the final blade 8 of this apron 5) and relative to which the latch 13 is mounted at least in rotation.

Regarding the stopper 14, it comprises at least one bearing surface 19; 19 ', defined at a rib 20; 20 'extending into a lateral slide 10, and with which 19; 19 'cooperates the latch 13, this in the locking position thereof.

In fact, such a rib 20 extends substantially perpendicular to a wing of a lateral slide 10 and / or substantially perpendicular to the plane in which the apron 5 extends.

As can be seen in the appended figures, such a stopper 14 comprises two bearing surfaces 19; 19 ', defined at two ribs 20; 20 'of this type which define an opening 21 for the passage of the apron 5 and / or for the passage of the latch 13 in the unlocked position.

According to another characteristic of the invention, the protection device 3 comprises at least one locking block 22, engaged inside a lateral slide 10, positioned at the lower end thereof, and at which at least one stopper 14 of a locking means 12 is defined.

A preferred embodiment of the invention consists in that this protection device 3 comprises two locking blocks 22 each arranged in a lateral slide 10; 10 '.

As discussed above, the control means 15 is adapted to control the rotation of the latch 13 from at least one locking position to an unlocking position.

However, and according to an additional feature of the illustrated invention figures 2 , 3 , 5 and 6 , the protective device 3 may also include means for controlling the rotation of the latch 13 from an unlocking position to a locking position. A preferred embodiment of the invention consists in that these control means consist of a single control means 15.

In this regard, it will be observed that the control of the rotation of this latch 13 (from a locking position to an unlocking position and / or vice versa) is, at least in part, provided under the effect of the movement of the deck 5 , more particularly under the effect of the deployment and / or folding of this apron 5.

Finally and as evoked above, the protective device 3 comprises a return means of the apron 5 in the folded position. Such return means advantageously makes it possible to exert traction on an apron 5 locked in an extended position by means of at least one locking means 12, this to make him adopt a closure position on openings.

In the remainder of the description, it will be more particularly described various embodiments corresponding to different types of embodiment of locking means 12 having the above characteristics.

So and according to a first type of realization illustrated Figures 2 to 4 , the latch 13 is only rotary type.

In this regard, it will be observed that the rotation of such a latch 13 operates in accordance with an axis substantially parallel to the plane of the deck 5 and the direction of extension of the end element 8 (more particularly constituted by a final blade) that comprises the apron 5. In fact, this extension direction is parallel to the longitudinal edge of the apron 5 (more particularly to the longitudinal edge of the end element 8 that it comprises 5) and, preferably, horizontal.

Such a latch 13 comprises at least one attachment means 17; 17 'adapted to cooperate, in locking position, with a stopper 14, more particularly with at least one bearing surface 19; 19 'that includes such a stopper 14.

The locking means 12 further comprises a shaft 23, associated with such a hooking means 17, 17 'and associated with the apron 5 by means of a mounting means.

According to a first illustrated embodiment figures 2 and 3 such a shaft 23 is made integral in rotation with such a hooking means 17, 17 'and is rotatably mounted on the deck 5 via the rotational mounting means 16. The latter 16 can take the form of an insert 18 provided with a piercing, a hole, channel or other for receiving, in rotation, said shaft 23.

As seen in these same figures, such a hooking means 17, 17 'may be constituted by a puck 24 (rectangular, square, trapezoidal ...) or be defined at such a puck 24.

Such a puck 24 is made integral with the free end of the shaft 23 (in particular made of material with this puck 24) and extends laterally relative to the shaft 23, preferably on either side of it. 23, especially symmetrically.

In such an embodiment, the means 15 for controlling the passage of the latch 13 of a locking position ( Figures 2c, 2d, 2e, 2f and 3a ) to an unlock position ( Figures 2, 2a, 2g, 2h , 3 and 3b ) and / or the passage of this latch 13 from an unlocking position to a locking position is constituted by a control finger 25 adapted to cooperate (in particular by pressing and / or pushing) with at least one lug 26 or analogous to the lock 13, this to cause the rotation of this latch 13.

As visible on the figures 2 and 3 , the latch 13 comprises a plurality of lugs 26 extending radially relative to the axis of the shaft 23 and regularly distributed, angularly (including equiangularly), with respect to this axis.

A preferred embodiment ( figures 2 and 3 ) consists in that the latch 13 comprises four lugs 26 equiangularly distributed so that two successive lugs 26 extend at 90 ° from each other, so as to cause a quarter-turn rotation of the latch 13 to each actuation by the control finger 25.

In fact, such lugs 26 are preferably defined at the level of the shaft 23 (in particular made of material therewith 23) or at the level of an element (toothed wheel, toothed gear or the like) associated with this shaft 23 and / or the means (s) of attachment 17; 17 ', such an element being integral in rotation with this means (s) hooking 17; 17 '.

With regard to the control finger 25, the latter, according to a first illustrated embodiment Figures 2 to 2h , is constituted by a rib extending substantially vertically, at the lower end of a lateral slide 10, this from a surface 27 including the threshold of the opening 2, the bottom of a lateral slide 10, preferably and preferably by the bottom of a locking block 22 ( figure 2 ) engaged in such a slide 10.

This rib is designed to cause rotation of the latch 13 under the effect of the displacement of this latch 13 (concomitantly with the deployment of the deck 5) in the slide 10 ( Figures 2a to 2h ).

As seen in these same figures, such a rib is inclined relative to the bottom of the slide 10 or the locking block 22.

A second illustrated achievement figure 3 to 3b relates to a control finger 25 constituted by a movable rod which comprises the means 16 for mounting the lock 13 in rotation.

This movable rod is designed to cooperate with a surface 27 in particular constituted by the threshold of the opening 2, by the bottom of a lateral slide 10, and preferably ( figure 3 ) with the bottom of a locking block 22 engaged in such a slide 10.

This movable rod is designed to cause rotation of the latch 13 under the effect of its displacement relative to the mounting means 16 (especially inside thereof 16, figure 3b ), this displacement being caused by the cooperation of this movable rod with the surface 27 under the effect of the displacement of the latch 13 (concomitantly with the deployment of the deck 5) in the slideway 10 ( Figures 3a and 3b ).

It will be observed that this movable rod is preferably completed by a return means (in particular constituted by its own weight or, preferably, by a means of elastic type, in particular in the form of an elastic blade) designed to repel this rod movable towards the surface 27 (in particular outside the mounting means 16), this after it has caused the rotation of the latch 13.

As mentioned above, the latch 13 comprises a shaft 23, associated with at least one attachment means 17, 17 'and the apron 5 by means of a mounting means, in particular in rotation.

According to a second illustrated embodiment figure 4 such a hooking means 17; 17 '(in particular in the form of a puck 24 or defined at a puck 24 as mentioned above) is rotatably mounted on the shaft 23 which is secured (fixedly) to the deck 5 and which constitutes, at least in part, the means 16 for rotating the latch 13 on the apron 5.

In such a case, the means 15 for controlling the rotation of the latch 13 at least one locking position ( Figures 4, 4a, 4f, 4g ) to an unlock position ( Figures 4b to 4e and 4i and 4j ), is constituted, at least in part, by means 28 of return of at least one attachment means 17; 17 'in an unlocking position.

As visible on the Figures 4a , respectively 4b, corresponding to the latch 13 in an equilibrium position (preferably corresponding to an unstable equilibrium position), respectively in an unlocking position (preferably corresponding to a stable unlocking position), the means 28 for recalling are constituted, on the one hand, by a flat 29 defined at the level of the shaft 23 and forming an acute angle with the plane of the deck 5 and, consequently, with the surface 27.

On the other hand, these return means 28 are constituted by a spring blade 30 associated with at least one attachment means 17; 17 'and adapted to cooperate with the flat portion 29 in an unlocked position of the latch 13.

As visible on the Figures 4c to 4j , this latch 13 is designed so that, under the effect of the deployment of the apron 5 ( Figures 4c to 4f ), this latch 13 cooperates with a surface 27 (of the aforementioned type) and so that, under the effect of this cooperation, this latch 13 adopts a position of equilibrium ( Figures 4a, 4f, 4g ), preferably unstable.

During a folding maneuver of the apron 5 from the surface 27 ( figure 4g ), the latch 13 (adopting a position of equilibrium) is brought to cooperate with the stopper 14 so that through this cooperation, the latch 13 is brought out of its equilibrium position, a part, to adopt a locking position and, secondly, so that it has a tendency to swing to go to an unlocking position in which the spring blade 30 cooperates with the flat part 29, this under the influence of recall means 28.

To do this and as visible on the Figures 4c to 4j , the stopper 14 comprises two bearing surfaces 19; 19 ', designed to cooperate with two attachment means 17; 17 'that includes the latch 13, defined at the two ribs 20; 20 ' extending inside a lateral slide 10 (in particular at a locking block 22) delimiting, between them, an opening 21 at least for the passage of the latch 13 in the unlocked position (or for the passage of the deck 5) and asymmetrical with respect to the opening 21.

During a deployment operation of the deck 5 from this locking position ( figure 4i ), the latch 13 completes to switch to its unlocking position to allow a folding operation of the apron 5 ( figure 4j ).

According to a second type of embodiment, illustrated figures 5 and 6 , the latch 13 according to the invention is of rotary type with respect to the apron 5 but, also and moreover, of sliding type with respect to this apron 5.

Such a latch 13 is then secured to this deck 5 by means of means 31 for mounting in translation, completing a means 16 for mounting this latch 13 in rotation.

In this regard, it will be observed that this rotation, respectively this translation, operate around, respectively, along an axis extending parallel to the plane of the deck 5 and longitudinally with respect to the lateral edge thereof 5.

A locking means 12 according to this second embodiment has been illustrated figures 5 and 6 and comprises, on the one hand, a latch 13 constituted by a "T" shaped piece 35 at the head of which is defined at least one hooking means 17, 17 'and, on the other hand, a rotational mounting means 16 and a translational mounting means 31 constituted by a means 37 for receiving the foot of the workpiece 35 "T" with the possibility of rotation and translation of this foot. Such reception means 37 is more particularly defined at an insert 18 engaged in an end element 8 of the apron 5.

As visible on the Figures 5 to 5 , 6a and 6b such a locking means 12 further comprises means 15 for controlling the passage of the latch 13 from a locking position ( Figures 5c , 6c ) to an unlock position ( Figures 5a, 5e , 6, 6b and 6d ) and / or the transition from an unlocking position to a locking position.

This control means 15 comprises, on the one hand and at the level of the piece 35 in "T", a guide cam 38 constituted by an impression (more particularly hollow and in the form of a guide path) made at the foot of the piece 35 "T", more particularly at a cylinder 39 associated with this foot and having a diameter substantially greater than that foot.

On the other hand, this control means 15 comprises, at the level of the receiving means 37 of the "T" part, a finger 40 designed to cooperate with said cam 38, under the effect of a translation of the workpiece. 35 "T" relative to the receiving means 37 (and, therefore, with respect to the finger 40), give this piece 35 "T" a rotational movement.

With regard to this receiving means 37, it adopts the shape of a cage 32 inside which is positioned (with the possibility of translation and rotation) the cylinder 39 of the "T" part 35. This receiving means 37 comprises, again, at least one opening, communicating with the cage 32, and traversed (freely in rotation and in translation) by a portion of the foot of the piece 35 "T". Such a receiving means 37, again, comprises or is defined at an insert 18 engaged inside a blade 6 of the apron 5, more particularly of the final blade 8.

According to another characteristic of this type of embodiment, the control means 15 is completed by an actuating means 36 designed to bear on the "T" part 35 (more particularly on the foot of the "T" part 35 or on the cylinder 39 associated with this foot) in order to cause a translational movement of this piece "T" 35 relative to the apron 5, more particularly to push this piece 35 "T" outside its receiving means 37.

Through such a translation, it is ensured, concomitantly, the rotation of this piece 35 "T" allowing, in particular to position the latch 13 in a locking position and / or unlocking.

Such an actuating means 36 is, in particular, designed to act on the T-piece 35 against an action (described below) exerted on the same piece "T", in support against the surface 27, by the deployment of the apron 5.

In fact, such an actuating means 36 is constituted by a biasing means, preferably of elastic type, which, in the illustrated embodiment figure 5 , respectively figure 6 , is constituted by a spring blade, respectively by a coil-type spring.

Yet another feature of this type of embodiment consists in that the locking means 12 comprises means 33 designed to hold the latch 13 in its position after having been brought by the control means 15.

Such holding means 33 is constituted by a particular configuration of the cam 38 (illustrated embodiments figures 5 and 6 ), possibly supplemented by ratchet type means (illustrated embodiment figure 6 ). Such a ratchet-type means is defined, on the one hand and at the level of the receiving means 37, by a flexible finger and, on the other hand, and at the level of the "T" -shaped piece (more particularly at its level). foot, including cylinder 39), by a plurality of lugs.

In the context of the operation of this second type of embodiment, it will be observed that, as a result of the deployment of the apron 5, the "T" part 35 enters, first of all, in contact with the surface 27 of the aforementioned type, depending on the case through the foot of this piece 35 "T" ( figure 5 ) or the head of this "T" Figure 6c, 6d ). Then and under the effect of the further deployment of the deck 5, this piece "T" is pushed, as appropriate, through ( figure 5 ) or inside ( figure 6 ) of the insert 18, this during a translational movement of the part "T" 35 relative to the receiving means 37.

Through this repulsion movement, the control means 15 partially rotates the "T" -piece 35 to an intermediate position between an unlocking position and a locking position. figure 5b - (Or vice versa - figure 5 ).

This follows a folding apron 5 during which intervenes the actuating means 36 which pushes the piece 35 "T" in an opposite direction (through- figure 5 - or outward - figure 6 - Of the insert 18), which, under the effect of the control means 15, completes the rotational movement of the part "T" 35 so that the latter 35 reaches the locking position ( figure 5c , 6c ) or unlocking (5a, 5e, 6, 6b, 6d).

It will be observed that this second type of embodiment proves, in fact, particularly powerful, enduring and reliable and is a solution particularly suitable for solving the problem according to the invention, more particularly from the mechanical point of view.

As mentioned above, the protective device 3 may be constituted by a shutter 4 but may also be constituted by a garage door, a blind, a mosquito net or the like.
